Genes affected
SMYD3 (HGNC:15513): (SET and MYND domain containing 3) This gene encodes a histone methyltransferase which functions in RNA polymerase II complexes by an interaction with a specific RNA helicase. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.688G>A (p.E230K) alteration is located in exon 7 (coding exon 7) of the SMYD3 gene. This alteration results from a G to A substitution at nucleotide position 688, causing the glutamic acid (E) at amino acid position 230 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
